CAI = Cold Air Intake
One thing that I would suggest with your size rig and seeing that you have a 4X4 re: maneuvering .....use 4X4 low for backing up 'any' slope. This will save (tranny) from over heating and give you nice slow control.
Note: I have disconnected the air tubes for switching on the fly to do this.
I just do the manual hub switch if and when I need true 4X4.
PS I even use 4X4 low for maneuvering into camp spots...it just creeps along at idle nice control. (front wheels disengaged)
